Senior Connected Firmware Developer

SharkNinja•Needham, MA

3d•$125,000 - $150,000•Onsite

About The Position

This is a hands-on connected-firmware role at SharkNinja where you will write the code that makes our products connect. You will be responsible for the connected features SharkNinja keeps in-house, including wireless connectivity, device provisioning and pairing, over-the-air updates, and differentiated connected experiences. You will also manage the platform layer that other connected programs depend on, such as connectivity stacks, provisioning code, and shared app/cloud integration components. The role involves building production connected-feature code end-to-end and creating reference implementations to prove out the architecture for all programs and partners.

Requirements

5+ years of embedded software and firmware development, with meaningful depth in wireless connectivity or connected-device features.
Experience delivering and shipping production connected firmware in commercial products.
Experience building to an architecture defined by others — implementing connectivity stacks, provisioning flows, or app/cloud integration from documented interface contracts.
Strong embedded C; C++ on resource-constrained platforms.
Knowledge of wireless connectivity technologies: Wi-Fi, Bluetooth/BLE, Matter, Thread, Zigbee.
Experience with device provisioning, pairing, and companion app integration: BLE GATT, Wi-Fi onboarding, cloud device registration and authentication.
Experience with Real-Time Operating Systems (RTOS).
Experience with Git-based workflows, CI builds (gcc, CMake, headless), unit testing (Ceedling or equivalent), static analysis.
Experience debugging on target hardware — oscilloscopes, logic analyzers, JTAG/SWD, trace.
Understanding of OTA update mechanisms and device security fundamentals for connected products.
Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related discipline required.
Competencies: Ownership and follow-through, technical rigor, clear written and verbal communication, collaboration across hardware, cloud, and mobile, standards discipline under schedule pressure.

Nice To Haves

Consumer electronics, IoT devices, smart home products, or comparable connected high-volume products (preferred).
CI/CD, automated testing, or build infrastructure for embedded systems (strongly preferred).
Reviewing or integrating code from external development partners (an advantage).
Display technologies and embedded graphics/UI frameworks (a plus).

Responsibilities

Design, implement, and debug production embedded firmware for connected consumer and home appliance products.
Manage connected features end to end, including requirements clarification, implementation, unit test, integration, and release support.
Develop in retained areas: wireless connectivity, device provisioning and pairing, OTA, and differentiated connected experiences.
Develop against the connectivity architecture, interface, and app/cloud integration standards, adopting platform components rather than rebuilding them.
Implement defined reference architectures and reference implementations for Bluetooth/BLE, Wi-Fi, Zigbee, Thread, and Matter stacks, plus provisioning and pairing code, for reuse across product categories.
Build and maintain shared connectivity and app/cloud integration components, including BLE GATT profiles, Wi-Fi onboarding, and cloud device registration.
Build to defined interface contracts and platform decisions.
Prototype new connectivity and app-integration technologies to de-risk decisions ahead of program commitment.
Participate in technical design reviews for internal and partner-developed connected firmware.
Review partner-delivered connected code and integrate it against SharkNinja standards.
Turn architectural intent into working reference code and shipped connected features that partners and other programs can build against without interpretation.
Support partner technical capability assessments for wireless and app-integration subsystems.
Write unit tests and maintain code coverage against the standard applied across internal and supplier code; resolve static analysis findings, with no unresolved critical or high-severity issues at release.
Build and maintain CI pipeline, static analysis configuration, and interoperability test-harness infrastructure for owned connected features and platform components.
Verify the reproducibility standard in practice — confirm that source, toolchain, and build manifest deliverables actually rebuild the shipping binary.
Work in feature branches with PR-gated merges, ticket-linked commits, and commit messages sufficient to generate release notes.
Work under the technical direction of Principal Engineers on connected platform capabilities and design review, building toward broader architectural scope over time.
Bring up firmware on target hardware and debug hardware-software-app integration issues with Hardware Engineering, Cloud, and Mobile App teams.
Support certification activities — Bluetooth SIG, Wi-Fi Alliance, Matter — with hands-on testing and issue resolution.
Coordinate with firmware engineers in other regions to drive continuous improvement.
